9父与子虽然是“一”〔约十30〕，二者却仍然有“我”和“父”的分别。这一点不能忽略，因为一忽略了，就会成为形态论者（modalist）。形态论主张这一位神有三个时期，并且互不同时存在。但圣经给我们看见，父、子、灵三者是同时存在，并且是存在彼此里面，所以父、子、灵三者是一，是一位神；但这一位神又是三，是父、子、灵。既是这样，父、子、灵什么时候是一，什么时候是三？……我们只能照着圣经的话说，这一位神有父、子、灵三者的讲究；这三者是绝对有分别的（distinct），却也是绝对不能分开的（separate）；并且这三者也是互相内在的，第一位在第二位里面，第二位又在第一位里面，而第二位子与第三位灵又是一个（林后三17）。因此，如果父、子、灵只是同时存在，就还有分开的可能；但是因为祂们又是互相内在，就没有分开的可能。因这缘故，神才是三一神。 9Although the Father and the Son are one [John 10:30], between Them there is still a distinction of “I” and “the Father.” We must not disregard this point, because if we do, we would become modalists. Modalism advocates that God, who is one, has three manifestations in three different periods and that the three manifestations do not exist within each other at the same time. The Scriptures show us, however, that the three—the Father, the Son, and the Spirit—not only exist at the same time but also exist in one another. Therefore, the three—the Father, the Son, and the Spirit—are one; They are one God. However, this one God is also three; He is the Father, the Son, and the Spirit. Since this is the case, when are the Father, the Son, and the Spirit one, and when are They three?…According to what the Bible tells us, we can say only that God is one, yet He has the aspect of being three—the Father, the Son, and the Spirit. These three are distinct but inseparable. Furthermore, these three exist within one another: the first is in the second and the second is in the first, and the second, the Son, and the third, the Spirit, are one and the same (2 Cor. 3:17). Hence, if the Father, the Son, and the Spirit only exist at the same time, They may still be separated; however, because They also exist within one another, They are inseparable. This is why God is triune; He is the Triune God.
